Of course, it is impossible to look inside a person’s head and study what role they are playing. All we can observe is behavior, or role performance. Role performance is how a person expresses his or her role. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman 1959). Think about the way you behave around your coworkers versus the way you behave around your grandparents versus the way you behave with a blind date. Even if you’re not consciously trying to alter your personality, your grandparents, coworkers, and date probably see different sides of you. As in a play, the setting matters as well. If you have a group of friends over to your house for dinner, you are playing the role of a host. It is agreed upon that you will provide food and seating and probably be stuck with a lot of the cleanup at the end of the night. Similarly, your friends are playing the roles of guests, and they are expected to respect your property and any rules you may set forth (“Don’t leave the door open or the cat will get out.”). In any scene, there needs to be a shared reality between players. In this case, if you view yourself as a guest and others view you as a host, there are likely to be problems. Impression management is a critical component of symbolic interactionism. For example, a judge in a courtroom has many “props” to create an impression of fairness, gravity, and control—like their robe and gavel. Those entering the courtroom are expected to adhere to the scene being set. Just imagine the “impression” that can be made by how a person dresses. This is the reason that attorneys frequently select the hairstyle and apparel for witnesses and defendants in courtroom proceedings. Figure 4.13 A judge’s gavel is known as a prop designed to add gravity and ceremony to the proceedings.

According to Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley believed that our sense of self is based upon this idea: we imagine how we look to others, draw conclusions based upon their reactions to us, and then we develop our personal sense of self. In other words, people’s reactions to us are like a mirror in which we are reflected.
